One more thing... Running EmuNand... How do I approach updating my system and running EmuNand Properly?
If you're a beginner I wouldn't do this immediately as you can accidently update your system.
But when your'e ready:
on GW menu, select format emunand (this erases everything on the big sd card so backup first)
boot gw and it should automatically boot into emunand (it will look exactly like regular nand at first)
go to system settings and check you firmware. (ONLY if GW3D is in front of your firmware version, go to the next step)
while staying in system settings, go to update system and update your system (DO NOT LEAVE SYS SETTINGS DURING THIS STEP)
the system will reboot after the update and you'll be returned to your previous firmware!
no fear, just reboot the gateway and you should enter your updated emunand (there may be a black screen for a while, just wait, emunand can be slow)
